Clinical & Coding Specifications
Clinical Context
A 42-year-old patient with recurrent otitis externa and chronic tympanic membrane disease presents for operative ear surgery under anesthesia. The otolaryngologist plans a tympanotomy with possible biopsy of an external canal lesion and inspection of the middle ear and inner ear structures. Preoperative evaluation documents bilateral sensorineural hearing loss (H90.3), intermittent tinnitus (H93.19), and a history of Meniere's symptoms (H81.09). The anesthesia team performs a focused pre-anesthesia assessment, documents airway evaluation, fasting status, and comorbidities, obtains informed consent for general anesthesia, and coordinates operating room resources.
On the day of service the patient receives standard ASA monitors, induction of general anesthesia, and airway management appropriate to ENT surgery (endotracheal tube). Intraoperative care includes maintenance of anesthesia, analgesia, and hemodynamic support through external, middle, and inner ear procedures (biopsy and tympanotomy). Postoperative handoff includes immediate PACU recovery, pain management plan, neurologic and otologic exam, and instructions for otolaryngology follow-up.
